7	 * <p>
8	 * We reserve no legal rights to the ANTLR--it is fully in the
9	 * public domain. An individual or company may do whatever
10	 * they wish with source code distributed with ANTLR or the
11	 * code generated by ANTLR, including the incorporation of
12	 * ANTLR, or its output, into commerical software.
13	 * <p>
14	 * We encourage users to develop software with ANTLR. However,
15	 * we do ask that credit is given to us for developing
16	 * ANTLR. By "credit", we mean that if you use ANTLR or
17	 * incorporate any source code into one of your programs
18	 * (commercial product, research project, or otherwise) that
19	 * you acknowledge this fact somewhere in the documentation,
20	 * research report, etc... If you like ANTLR and have
21	 * developed a nice tool with the output, please mention that
22	 * you developed it using ANTLR. In addition, we ask that the
23	 * headers remain intact in our source code. As long as these
24	 * guidelines are kept, we expect to continue enhancing this
25	 * system and expect to make other tools available as they are
26	 * completed.
